Chapter 13: Stage 2 — Visa Approval

This chapter walks through Stage 2: the session-based OID4VP + OID4VCI flow. The embassy officer creates a session, the wallet presents a selective disclosure of the passport, the backend verifies the SD-JWT signature, the officer approves, and the visa is automatically delivered to the wallet via a credential offer — no second QR scan needed. Explains session state polling.

Coming soon.
